Kim Hyun-ah, better known by the mononym Hyuna, is a South Korean singer-songwriter, dancer, rapper and model. She rose to fame in the late 2000s as a member of the girl group Wonder Girls. After leaving the ensemble shortly after their debut in 2007, Hyuna subsequently joined the girl group 4Minute in 2009. She began her solo career in 2010, with a style she described as "performance-oriented music". Hyuna's debut single, "Change", peaked at number two on the Gaon Digital Chart.
She released her first extended play, Bubble Pop!, in 2011. Though the EP was a moderate seller, its title track sold more than 2.5 million copies, and Hyuna became the first female K-pop solo artist to reach 100M views on a single YouTube video. In 2012, she appeared in Psy's worldwide hit "Gangnam Style", which also led to a successful duet rendition of the song. Hyuna's second EP, Melting, saw her first number one entry on the Gaon chart with the single "Ice Cream".
Following 4Minute's disbandment in 2016, she released her fifth EP, A'wesome, which was supported by her first concert tour of the United States.
